  isascii: stop using it
  
  * doc/pastposix-functions/isascii.texi: There is no isascii module.
  * m4/mbswidth.m4 (gl_MBSWIDTH): Do not check for isascii,
  as it no longer seems to be used here.
  * tests/test-c-ctype.c (test_agree_with_C_locale):
  Do not assume isascii exists, as POSIX no longer requires it.
